Visa GiftCard + Ebay "Buy it now!" = **bleep**ed

Visa GiftCard + Ebay "Buy it now!" = **bleep**ed

I made a Paypal account to buy things with my visa giftcard; a movie and a game that I chose "Buy it now!" for. Because my card was registered and everything, I thought the purchase would go smoothly and quickly, but I didn't know my card wasn't verified. I'm a college student without a bank account or a credit/debit card, so there isn't any way of me being able to verify. However, I'm committed to these Buy it Now items, because I Bought Them Now. I'm committed to them, can't pay for them because I'm not verified and I can't verify. I'm completely boxed in. What should I do?
